A questo punto un "ceph versions" dovrebbe fare vedere gli MDS. Credo sia normale che non si vedano con un "ceph status" (quelli si vedono solo dopo che ho creato il file system
Credo i pool per dati e metadati:

ceph osd pool create cephfs_data 32 32
ceph osd pool set cephfs_data crush_rule replicated_hdd
ceph osd pool create cephfs_metadata 32 32

Dovrei ora vedere un MDS active e uno in standby:

cephfs:1 {0=c-mds-01=up:active} 1 up:standby |
Creo un client per questo filesystem:
